Explosive Environments
Gas Stations and Explosive Atmospheres
In locations with potentially explosive atmospheres, obey all
posted signs to turn off wireless devices such as your device or
other radio equipment.
Areas with potentially explosive atmospheres include fuelling
areas, below decks on boats, fuel or chemical transfer or
storage facilities, areas where the air contains chemicals or
particles, such as grain, dust, or metal powders.
Blasting Caps and Areas
Power off your device when in a blasting area or in areas
posted power off “two-way radios” or “electronic devices” to
avoid interfering with blasting operations.
